Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims priority from U.S. Provisional Patent Application No. 60/713,450 filed on Sep. 1, 2005, which is hereby incorporated by reference herein.
  • FIELD OF INVENTION
  • The present invention relates generally to ramps, and more particularly, to ramp kits of ramp components packaged in a disassembled condition for shipping and storage.
  • BACKGROUND OF THE INVENTION
  • Numerous types of ramps are used to assist in the loading and unloading of objects from elevated positions, including transportation vehicles. Particularly, trucks, vans, trailers and the like utilize ramps to assist in the loading of objects such as ATVs, motorcycles, lawnmowers, etc. Due to the required length of these ramps, it is advantageous that some ramps are foldable so as to increase their use length and decrease their storage length, while other ramps may be one-piece units. One such foldable ramp is disclosed in commonly assigned U.S. patent application Ser. No. 10/900,023, entitled Foldable Ramp Having Rung Hinge filed on Jul. 27, 2004 (U.S. Publication No. 20050055783, published Mar. 17, 2005), and herein incorporated by reference herein.
  • Most ramps are typically manufactured from aluminum to promote a light ramp with overall strong properties. Therefore, a user can lift or unfold a ramp alone when loading or unloading a vehicle from a transportation vehicle. Further, these ramps are often welded together which increases the costs associated with manufacturing the ramps and also requires skilled personnel to operate the welding equipment. However, these ramps may also be riveted together. Again, such construction techniques require special rivet fasteners that must be installed by trained personnel. As such, the method of manufacture greatly increases the time and cost associated with producing such ramps.
  • Further, ramps manufactured by welding or riveting are shipped and sold in their end-use, constructed state, which makes transporting the ramps particularly cumbersome and expensive given their overall shape and length. And should a portion of the ramp bend, break, or be damaged during shipping or use, the ramp is often discarded in its entirety or attempted to be fixed in any unconventional manner.
  • SUMMARY OF THE INVENTION
  • The invention disclosed herein overcomes at least some of the disadvantages associated with the prior art by providing a ramp kit of ramp components packaged in a disassembled condition for ease of shipping and storage. Such a kit permits the ramp to be manufactured with replaceable parts and shipped disassembled so as to reduce packaging and shipping sizes. Also, such a construction permits the user to assembly the ramp after purchase and properly repair the ramp if required from available replacement parts.
  • A ramp kit of ramp components packaged in a disassembled condition for shipping and storage generally comprising a plurality of elongated side members, a plurality of cross members having an integrally formed fastener engagement boss, and a plurality of threaded fasteners for connecting the cross members to the elongated side members to assemble the ramp. The ramp kit may also include a drive member for installing and removing the threaded fasteners as well as components being configured to be capable of nesting along their lengths to reduce the shipping size of the disassembled components.
  • The invention will be more fully described in the following written description with reference to the accompanying drawings.
  • BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING
  • FIG. 1 is a perspective, underside view of a foldable ramp in an assembled state.
  • FIG. 1A is an exploded view of the ramp shown within circle A of FIG. 1.
  • FIG. 2 is view of the bottom section of the ramp of FIG. 1 showing the hinge device.
  • FIG. 3 is a partially exploded view of the top section of the ramp of FIG. 1.
  • FIG. 4 is a partially exploded view of the bottom section of the ramp of FIG. 1.
  • FIG. 5 is a segmented view of the cross member of the ramp of FIG. 1
  • FIG. 6 is a segmented view of the end support member of the ramp of FIG. 1.
  • DETAILED DESCRIPTION OF THE INVENTION
  • The ramp described herein is capable of being manufactured and shipped in an unassembled condition so as to keep the packaging and shipping sizes as small as possible. Therefore, the ramp is intended to be assembled by the customer, possibly with tools supplied with the ramp kit. Further, any damaged components can be removed or desired changes the configuration of the structure can be accomplished by user disassembly of the ramp and replacement of components. This is a distinct advantage over previously constructed welded and riveted ramps. And while the preferred embodiment of the invention is directed to a foldable vehicle ramp, it should be clear to anyone reading and understanding this description that the invention could be utilized for any type of ramp whether foldable or otherwise and that the following description of the preferred embodiment should in no way limit the scope of the invention or the claims as appended.
  • Referring now to the drawings, and in particular to FIG. 1, a ramp, generally designated 10, includes a first or upper ramp section 12 and a second or bottom ramp section 14. The first and second ramp sections 12,14 are pivotally connected to each other by a hinge 16. As shown in FIG. 1A, the hinge 16 comprises a pair of brackets 18 connected to the inner surface of the side members 20 of both the first and second ramp section 12,14. Each hinge bracket 18 preferably comprises an A-shaped member having apertures therethrough for connecting to the first or second ramp members 12,14. For example, as best shown in FIGS. 1A and 2, one side of the A-shaped bracket 18 is bolted to the second ramp section 14 by a two-bolt connection while the other end of the bracket 18 is pivotally connected to the first ramp section 12 or visa versa. Therefore, one of the ramp sections can pivot relative to the other ramp section so that the ramp 10 can be positioned between an extended, operable position shown in FIG. 1 and a folded, storage position (not shown).
  • The first ramp section 12 (shown in FIG. 3) and the second ramp section 14 (shown in FIG. 4) are constructed having similar components, namely, a pair of elongated side members 20, rungs or cross members 22, and an end support member 24. Side members 20 comprise elongated tubular members having a longitudinal channel 26 located on an inner surface thereof. The end support member 24 and the cross members 22 each have predetermined lengths, first and second ends, and a fastener engagement boss 36 integrally formed therein. The ends of end support member 24 and cross members 22 are capable of nesting within the longitudinal channels 26 of the side members 20 and being connected thereto through mounting apertures 28.
  • As best shown in FIG. 5, the cross member 22 comprises an elongated tubular member having a support surface 30, a pair of side walls 32, a base 34, and a bolt engaging boss 36 (a C-shaped channel at a central portion thereof for receiving a self-tapping screw). Preferably, the elongated members 20, the cross members 22, and the end support members 24 are each integrally formed from a light-weight material, preferably extruded aluminum, while any other suitable materials can be used. The end support member 24, as best shown in FIG. 6, comprises a box-shaped base 40 having a fastener engaging boss 36 therethrough and an inclined surface 44 extending therefrom. All of the components of the ramp 10 are preferably manufactured from aluminum so as to provide a lightweight component having a high strength level.
  • The ramp 10 is constructed wherein self-tapping screws 46 are inserted through the mounting apertures 28 of the side members 20 and engage the fastener engaging bosses 36 formed in the cross members 22 and end support member 24. Each cross member 22 and end support member 24 has screw bosses 36 formed during the aluminum extrusion process. The ¼-20×¾ zinc plated steel torx pan head type F screws 46 are self tapped into the bosses 36 using a hand tool or power tool bit which could be supplied in the ramp kit. The side members 20 are tightened to the cross members 22 and to the end support member 24 to form the upper ramp section 12 and lower ramp section 14. Such a novel construction permits ease of assembly and disassembly so that the ramp 10 can be shipped disassembled to the customer for assembly, thus saving packaging and shipping space, as well as permitting the removal and replacement of damaged components. The screw design permits the ramp to flex under heavy loads with no weld stress points so the ramp can achieve a higher load rating (no welding failure).
  • As indicated above, the particular ramp design and construction enables the components to be prefabricated and packaged in a disassembled condition for shipping and storage in a ramp kit and assembled by the end user. Due to the disassembled construction and the nestable configuration of the ramp components, the ramp kit takes up substantially less shipping and storage space as opposed to the previously welded or riveted ramp constructions.
  • As such, a ramp kit of ramp components packaged in a disassembled condition for shipping and storage generally comprises a plurality of elongated side members 20, a plurality of cross members 22, and a plurality of threaded fasteners 42 for connecting the components. It is likely that the ramp kit would also include a tool as part of the ramp kit to enable the user to assemble and disassemble the ramp. However, depending upon the type of fasteners used, the ramp kit may not include a tool in that the user may be able to use a simple wrench or screwdriver to assemble the ramp.
  • The elongated side members 20 each have a predetermined length and a longitudinal channel 26 along their lengths. Any number of side members 20 can be provided having any number of predetermined lengths. As indicated below, due to ramp sections constructed with pairs of side members, it is preferable that there be at least two side members of similar length. At least one mounting aperture 28 is provided in the side members to connect the side members 20 to the cross members 22 and end support member 24. Preferably, the mounting apertures 28 are located systematically along the side member 20 to provide proper spacing for the cross members 22. Further, additional mounting apertures 28 may be provided so that additional cross member configurations can be achieved as desired 16. The side member 20 also includes an upwardly extending side structure 29 extending along its length to provide a wall to prevent the accidental movement of an object off of the surface of the ramp.
  • The cross members 22 also have a predetermined length and a first and second end. Again, any number of side members 20 can be provided having any number of predetermined lengths. A fastener engagement boss 36 is integrally formed within the cross member wherein the ends are capable of insertion within the corresponding longitudinal channels 26 of a pair of side members 20 so that the fastener engagement bosses 26 align between corresponding mounting apertures 28.
  • The threaded fasteners 42 are each capable of insertion within the mounting apertures 28 of the side members 20 and engagable with the fastener engagement bosses of the cross members 22 and end support members 24. Any kind of threaded fastener can be utilized having any type of drive means, including Phillips, Standard, Hex-head, star-shaped, or any other know driving surface configuration. If a tool in included with the ramp kit, it would be required to engage the driving surface as provided.
  • The ramp kit and therefore the ramp 10 may or may not include at least one end support member 24. The end support members 24 are of a predetermined length having first and second mounting ends. A fastener engagement boss 36 is integrally formed within the first and second mounting ends so that the fastener engagement bosses 36 align with the mounting apertures 28 or the side members 20. Therefore, the ends of the support members 24 are capable of insertion within the corresponding longitudinal channels 26 of a pair of side members 20 and fastened thereto to assemble the ramp 13. As shown in FIG. 6, the end support member 24 preferably includes a lip portion 44 extending along at least a portion of the length of the body 40 and extending outwardly therefrom at a predetermined angle.
  • Preferably, the ramp kit provides the assembly of a ramp having pivotable upper and lower ramp sections. As described above, an upper ramp section 12 comprises a first pair of side members 20, a plurality of cross members 22. At least one support member 24 may also be utilized to form the upper ramp section 12. A second pair of side members 20 and a plurality of cross members 22 form a lower ramp section 14. A hinge device 16 joins the upper ramp section 12 and the lower ramp section 14 to create a pivotable ramp sp that the ramp sections 12,14 are pivotable between an extended, working position and a collapsed, storage position.
  • Of significant importance related to the reduced shipping size of the ramp kit, the components are configured to provide nesting during packaging and shipment. Particularly, the longitudinal channel 26 of the side members 20 and the cross members 22 and end support members 24 are configured such that the cross members 22 and the end support members 24 are capable of nesting along their lengths within the longitudinal channel 26 during packaging and shipment. Therefore, as the packaging size of the ramp is greatly reduced by provide a disassembled ramp kit, the packing size if further reduced by configuring several components to nest together thereby additionally reducing packaging space.
  • The invention has been described with reference to the preferred embodiment. Obviously, modifications and alternations will occur to others upon a reading and understanding of this specification. The claim as follows is intended to include all modifications and alterations insofar as they come within the scope of the claim or an equivalent thereof. Having thus described the invention, I claim:
